Mingliang Carbon Fiber (Jilin) Co., Ltd. grows together with the domestic carbon felt industry. Since the beginning of the domestic carbon felt industry in 2005, the company has begun to use pre-oxidation and carbonization production equipment for carbon-fed carbon felt, and is in a leading position among domestic carbon felt production equipment. At present, about 70% of domestic carbon felt manufacturers use their production equipment. In 2017, the company began to develop and produce a new type of modified "pre-oxygenated carbon felt". Its performance is much higher than the original domestic acrylic carbon felt, which can replace the expensive imported carbon felt, and the price is about 1/3 of the imported carbon felt. The current annual production capacity is 3,000 tons.
